I agree, and generally I think the "trick" is found in creating two army lists, one of modern units, and one without modern units (But with the old bio-slug-tanks, and the "Hydraphant").
But by taking that route, don't you risk the modern list being outclassed by the list that contains things tailor made for Epic?
I mean, if the inclusive list has larger WEs, longer-ranged artillery, and dedicated AA, while the modern list either lacks those things, or stretches to fit them into some codex creature's statline, then the inclusive list will still be a more satifying list. That's because the inclusive list can both accurately model the codex creatures stats and include additional creatures to fill in the gaps. Otherwise, you end up with situations like the one that gave the zoanthrope its AA attack, because you only have codex creatures available to cover all Epic bases.
Also, the more I think about it, the more I disagree with the assertion that the old AV-class beasts have morphed into the new, WE beasts. I mean, just because they have similar weapon loads doesn't mean they are a direct equivalent. By turning all the old beasts into WEs, you seriously reduce the number of those beasts that a player has available during a game. You also create a gap in the middle of the scale continuum. Most mature army lists have a lot of infantry types, slightly fewer LV/AV types, and even fewer WEs. Stripping out the old AV-beast from the Tyranid list leaves the list top heavy, or forces you to include multiple variants of the remaining AVs to make up the short fall.
Similarly, if you block the inclusion of even larger creatures, then the list will lack parity with the other armies. And you can't even justify that with the fluff, because there are clearly things in the background that are so large that they can't even fit in the scale of a 6mm game, much less a 28mm one.
